Question

Both Parent Plant 1 and Parent Plant 2 have flowers that are pink. Each has a dominant Red allele and a dominant White allele. Neither allele alone can produce enough pigment to be either white or red, so the flowers are pink. Complete the Punnett Square to answer the questions.

R W

W RW
R


Flowers that have two W alleles will be ?




pink

white

green

red

Answer 1

Complete Punnett square:

- Top: R | W
- Side: R | W

Squares:
- R × R = RR → red
- R × W = RW → pink
- W × R = WR → pink
- W × W = WW → white

So flowers with two W alleles (WW) will be white.
